The things that happen in your life are either your choices or opportunities and lessons the universe has put before you. Life on earth is like college and we're all just trying to pass the courses.
I have no friends and I never leave my house. You just have to make a choice to just refuse to be involved with things that could get you in trouble. It's easy when you feel upset or depressed about something to want to go to a club and want to drink, but instead I just force myself to sit and feel it and deal with it, and try to grow from it, because I don't want to go down that path. I'm one of the most isolated people in existence right now, but it's worth it because if I wasn't making that decision I would be throwing away my career.
